Backronym of the year
« previous post | next post »
…is ACHOO — "Ever sneeze immediately after stepping into the sun? It's not a coincidence":
Picture this: You walk out the door on a bright, sunny morning. And before you’ve even reached the car, you sneeze. Maybe even two or three times in a row.
It’s not allergies, and it’s not a coincidence. It’s a real reflex, called the photic sneeze reflex.
By some estimates, it affects roughly one in four people.
Researchers have studied it for decades and have even given it a punny name: ACHOO syndrome, short for Autosomal Dominant Compelling Helio-Ophthalmic Outburst
The article goes on to explain that "The leading theory is that the optic nerve, which senses that sudden shift in light, runs right next to the trigeminal nerve, which is responsible for sensory information from the face and head, including triggering a sneeze. "
Wikipedia tells us that
A backronym treats an already existing word as an acronym and expands its letters into the words of a phrase, and so is effectively an acrostic. The word is a portmanteau of back and acronym. Backronyms may be invented with either serious or humorous intent, or they may be a type of false etymology or folk etymology.
A normal acronym is a word derived from the initial letter(s) of the words of a phrase, such as radar from "RAdio Detection And Ranging".[3] By contrast, a backronym is "an acronym deliberately formed from a phrase whose initial letters spell out a particular word or words, either to create a memorable name or as a fanciful explanation of a word's origin". Many fictional espionage organizations are backronyms, such as SPECTRE (SPecial Executive for Counterintelligence, Terrorism, Revenge and Extortion) from the James Bond franchise.
I've participated in a number of backronymically-named projects over the years, most recently STELLAR ("Steering-Vector Enhanced LLM Agents for Realistic Digital Twins in Mental Health"). The LDC's past-projects page lists quite a few others.
There don't seem to be very many relevant past posts, but here are a couple:

The earliest backronym that I am sure of is CARE, the Cooperative for American Remittances to Europe, now called the Cooperative for Assistance and Relief Everywhere, formed in 1945.
One that might be older is the UK First Aid Nursing Yeomanry, founded 1909. It seems that that somewhat unusual collocation must have been chosen to be pronounced Fanny, which presumably did not have its modern UK meaning at the time. A 1917 book called "Nursing Adventures: A F.A.N.Y. in France" definitely suggests (because of the "a" not "an") that at least by then it was pronounced Fanny and not Effayenwye, but doesn't establish that it was named with that pronunciation in mind,

There's the Racketeer Influenced and Corrupt Organizations Act (RICO), the federal anti-organized crime statute, and state analogues. I had an active civil RICO practice back in the day, and although I've always been slightly put off by the not-so-sly stereotyping of what happens to be my own ethnic background, I still have to admit that, as (b)ac(k)ronyms go, it's good … damn good.

As a T.O. ("Technical Officer") in what was then the GPO ("General Post Office"), I was responsible for leading a small team who were developing electronic circuitry to remotely select between a number of possible multiplexed sources, known as "aggregates". The overall head of the project was Dave Barber, to whom I reported, and I therefore named the project "Barber's Aggregate Remote Selection Equipment", which was usually abbreviated to "Barber's ARSE".

almost as old as CARE is the early computer name MANIAC, a backronym for Mathematical Analyzer Numerical Integrator and Automatic Computer. MANIAC I was built in 1950-51, but the name probably dates to its design and funding in the late 40s.

I don’t even remember if I assumed Apgar was a name or an acronym, but it’s both, and the only backronym I know of that’s a name https://en.wikipedia.org/wiki/Apgar_score

the early computer name MANIAC
Surely the name was a response to ENIAC 1945. Those guys seem to have missed an opportunity.
(Also Brits would challenge that claim "the first programmable, electronic, general-purpose digital computer,". Arguably, that was Colossus 1943 used for breaking ciphers, built at Bletchley Park, but whose precise details were suppressed by HMG for many years.)

Bills introduced to US legislatures often have backronyms for names. The latest example at the federal level may be the SAVE Act.
A bass-ackronym, surely.

CuConnacht – Fanny was of course the standard nickname for Frances for centuries (as was Dick for Richard). It's only in quite recent times that both have become virtually unusable as names.

"Dick" is still commonly encountered as a man’s name in the U.K., Kate.

'Backronyms' today are generally not only contrived to match an appropriate existing word, but are taken seriously. MANIAC the computer fails that: yes, it was one of a long list of computer names inspired by ENIAC, but not a word that would be used seriously in the context, and is generally said to be a protest against this naming of computers. (Scientific equipment – and many early users would consider computers such – had traditionally not been given any proper names, at least none that anyone would use formally.)
Possibly the case in the OP is a similarly silly-sounding protest against backronyms, as the phenomenon has an existing name, given in the text even, and the new name does not seem serious or likely to be used. Such a protest would be entirely warranted in my opinion, as I've never liked backronyms, nor the idea that some things _have_ to be given one.

I've heard tell that munge has been backronymmed as "Munge Until No Good." Also recursive. The final "e" seems to have been forgotten in that interpretation.
For those unfamiliar with the term, it refers to making a computer file unusable bit by bit rather than all at once, as it "This file has been munged."
Chas Belov said,

Standing (or sitting) possibly corrected, as Wiktionary says it's a forward acronym.
Philip Taylor said,
September 8, 2026 @ 3:09 am
I thought that the verb was "to mung", Chas, not "to munge". Which may explain why I have always assumed that it would be pronounced with a hard "g". Would you expect it to be pronounced with a soft "g" ?
Chas Belov said,
September 8, 2026 @ 5:04 pm
@Philip Taylor: I believe both spellings are extant, and certainly "mung" is truer to the recursive acronym. I've always said it with the soft g, and while I have rarely heard it aloud from others – if ever – I don't ever recall hearing it with a hard g. I'd guess if one spells it "mung" and pronounces it with the hard g, one would need to spell the past tense as "mungued" to keep the hard g sound.
Andrew Usher said,
September 8, 2026 @ 7:50 pm
Absurd; 'mung' does not have a g sound at all, and it would not be necessary to spell the past tense 'mungued' any more than the past tense of 'belong' should need to be 'belongued'. As the Wiktionary entries (already mentioned) say, the variant 'munge' is presumably due to some people seeing 'munged' in writing and not knowing which of the two possible pronunciations (hence root forms) was correct.
Also, I don't think the concept of a 'forward acronym' is useful, or at least I've never seen a case where it would be. Sure, one can concoct an acronymic etymology for an existing word, but that doesn't change the status of the _word_ as non-acronymic, and 'mung until no good' is clearly not meant to be a serious etymology anyway.
Philip Taylor said,
September 9, 2026 @ 2:54 am
" 'mung until no good' is clearly not meant to be a serious etymology anyway" — why not ? Is it not directly analogous to "Gnu [is] not Unix", and all the other in-jokes of the hacker community ?
Andrew Usher said,
September 9, 2026 @ 7:49 am
Isn't a joke, 'in' or otherwise, not serious by definition?
Andrew Usher said,
September 9, 2026 @ 7:46 pm
Clearly that was incomplete – a word coined genuinely as an acronym, even if a joke, would still be an acronym and recounting that as the etymology thus serious. But while that might apply to 'GNU' (created as the name of an organisation), it seems very unlikely for 'mung' – as Wiktionary says, also giving 'mash until no good' as an alternative acronymic explanation.
The Jargon File gives both 'mung' and 'munge', with possible non-acronymic etymologies, and also states 'mash until no good' predated 'mung until no good'. If there's no knowledge of the _actual_ etymology, explaining it as a silly acronym is humor rather than 'serious etymology'.

Andrew Usher,
Ah, but can't too the unserious be a proper object of study? Ziggy F. had a whole bit on "the Joke", and he was just about the most humorless person I can think of.

Wikipedia describes the USA Patriot (Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism) Act as a backronym,
Andrew Usher said,
September 12, 2026 @ 7:52 pm
'USA Patriot Act' is indeed among the clearest possible examples of a backronym. Surely there's some other point than simply that fact, is there not? You did end with a comma …
Benjamin Orsatti:
Of course there's nothing particularly wrong with studying the unserious as such (though perhaps it shouldn't be taken too seriously). That isn't relevant to allowing the unserious to be taken for serious, as was the hypothetical in this case.

How do you remember the order of the planets? I was taught this
My Very Earthly Mother Just sold Us Nine Pickles
Mars, Venus, Earth Mercury , Jupiter, Saturn, Uranus, Neptune, Pluto.
Too bad all those planets aren’t still here.
